I am going to debate you for two reasons
1. you have killed a bunch of deer, and great bucks
2. I see more ppl shooting deer too far back because they are so worried about the should.
IMO if you dont hit the deer high, and its within 30 yard, no matter the BH you are going to bust through that bone, and kill that deer. I personally am trying to do more of what your are doign with your Aim Point Kaiser. I think thats a darn good habit, and it has worked for you over and over again from what I have seen.
PS I shoot ( rage hypodermics, not starting a BH debate)
